Best K-5 settings for smaller file sizes? Trying to set up DIY photo booth

Isn't there any mini HDMI - lightning cable you could use to set the ipad as an external monitor? I would look in to that.

As for the quality, I used to develop RAW in camera and export then to a mobile with an eyefi card, using the 2mp+4star quality, just to post it to Instagram, and that work just fine on smartphone screen and even print then in 4x6, so I think this will do just fine for you if you still wanted to send then wirelessly to the pad.

Never had this problem with mine K3 ltd silver, wich is less than a year in my hands and now with fw. 1.4. And I abuse it a lot, plenty of shoots in cont H.

Is exposure linked with af point?
Check Custom menu pg 1 item 5.
Usually, I let this option turned off, in matrix meter and focus sel.

70-200 AF issue

Happy to know it was "just" this. But my opinion is this is one design flaw. As I noted, it has happened with a brand new D-FA* 50mm (can't find the original post). And also with my 16-50 (broke the 2 contacts altogether), although this one is 7yrs old and hacked to screwdrive, so no problem doing AF.

I'm keeping eye on this 70-200 lens, cos I planning to buy it someday, but here in my country we have none pentax servicing for newer lenses, so reliabillity is a concern.

Glad to know, failures are really unlikelly with those now.


edit: I was thinking...maybe one could put a very little drop of superglue BELOW the contacts, to fix it in place and diminish the odds of then to bend over again...should it work?

Its a long shot, but, the SDM contacts are intact? I saw one guy who bought a new D-FA* 50mm that had the contacts of his lens broken.

And what you mean by "pepperberry farm? I'm not northamerican (nor english native) and was just curious about what that means.

I quite like mine 16-50. Use an abuse it a lot. Like the sharpness, but CA is really ugly at wide settings. But I don't think turn it a 18-50 would cure those optical problems. I'm sure Ricoh can design one 16-50 with a much better control over aberrations.

Besides that, 16-something is an ideal range to a standard pro-grade zoom lens, and I think it wouldn't dissonates all that much overlaping with the new 11-18.

But if all they could do was updating its design with a much stronger body and better af, I think that won't be all that bad. After all, the problem that really turn people away from the original DA*16-50 was the bad SDM. And as soon as we discovered that screwdrive conversion hack, suddenly the lens got its value back.

Hood on the FA31

Well, look again at my lens and the thread is not a part of the hood piece. You can remove the hood and keep the thread.

But the lens will still be exposed, as the hood also covers the focus group helicoids. A replacement tube will still be necessary, to protect the innards of the lens.

ps: sorry guys, no pics of the thing. I don't like to disassemble the FA31. It's kinda painfull :lol:

---------- Post added 03-14-19 at 09:16 AM ----------



It's usually a plastic tube, of the same diameter of the ring. You press it against the ring and turn it. I use a spare plastic tube from my scratches, that had the same diameter of the inner ring. This vanity ring have no marks or holes to pick to turn it.

---------- Post added 03-14-19 at 09:44 AM ----------



I kinda like the way the flare happens with the FA31. Sometimes gives a moody atmosphere, an old 'hipsterized' look, withouth any kind of filter or processing.

Hood on the FA31

I accidentally dropped mine FA31 and 2 of the 3 screws that hold the hood brooke, so I had to discover how to disassemble it to replace then.

It is fairly simple to do. There is a ring, I think people call it 'vanity ring'. It can be unscrewed with a pressure tool. Beneath it, there are the screws that hold the hood.

That being said, removing the hood will let the front element much exposed and unprotected. If some want to remove it, will also have to make some kind of replacement tube, as the filter thread will also be removed, because it is a part of the hood.

But the hood on the 31 is so well made and an elegant part of the lens, I don't se the point in get it off.

But yes, it is removable.

PS: The lens survided, it have some nasty scratches, but it works and is fine now.

CP+ interview question suggestions

-Is there a plan to update the old DA* lenses? Or to replace with something entirely new?

-Did you consider giving to the possible APS-C flagship (a K3-III or whatever it is), more processing power? Enough to handle faster AF-C, faster image processing and better pixel shift?

-Did you consider using touch screen on you cameras? And how would you implement user's interface to take advantages of this type of user interaction?

- I want joystick to select af points. With possibly more af points in a still rumored APS-C flagship, did you consider implementing it?


I believe that a DA* 16-50 mkII and a DA* 50-135 mkII, with new AF drive (maybe the new ring type driving the D-FA* 50) and updated contruction will be hot sellers. I would buy the 16-50 in a heartbeat!

More processing power could lead pentax to a better position. APS-C market is fiercer than ever, and Ricoh must keep competitive to still be an option.

Touch screen would be a bonus.

The FA31mm has no sealing ;)
But it was serviced.

The wobling is caused by the rollers of the helicoidal on the focus group beig worn out. The technician I send it said he can't find a replacement. I live in Brazil and servicing pentax lens here is close to impossible, so I got it back with the best he could do to adjust it.
The lens is fine, but sometimes things that are focused in the right/up side of the finder will be soft if I shot wide open, in portrait orientation. In lanscape, everything are fine.

K-3 ii successor? Just curious...

Ricoh stated several times that KP is not the replacement for K-3 line. They are two totally different camera philosophies.


This was a misunderstanding and were never said in any of their marketing material.


Also, it's hard to believe either that the K1 would replace K3 as a flagship, because they are also of two distinct kind of cameras.

I think Ricoh tried to kill their flagship aps-c, keep the midrange with a more or less advanced camera, to save resources, but the somewhat cold reception of KP and the moan from people like me and many other, that want a true K3II successor, made then rethink their strategy, and resume the K3II replacement.

I think the cat and the BW portrait turn out really good. But I share some of your concerns.

Mine copy was great, but over time it developed some wobling in focus ring, that sometimes, in portrait orientation, affects focus precision and everything shot at f1,8 will be soft. Specially after I droped it on the floor one day. The lens survived, but I have some issues sometimes.

That beig said, I recomend you don't give up the FA 31mm so fast. Even considering the fact it is a 1990's era design, the lens really performs amazingly well for today's standards.
My opinion is, optically the lens is as best as a lens can get, but need a much more precise af system to perform better with those high resolution cameras we have today, as I fell that much of the oof focus is because screwdrive can't match the precision it needs to deliver crispy sharpness in a body like K1, or so.

But if after all, you really don't like it, I believe you won't have much problem in get rid of it.

One more time: DA* 16-50mm vs. Tamron 17-50mm F2.8 (AF adjustment)
Posted By sungibr

I have the 16-50 and use it extensively.

From my experience, the the major problem of get a reasonable af calibration is decentering. And the 16-50 is famous for that.
If you could get yours serviced, try to look for decentering. If you copy are defective, it'll be almost impossible to get a decent calibration.
I get mine somehow adjusted and now are pretty much fine. Reasonable sharpness on 50mm f2,8 and very good upwards.

Also, if that's not the case, doing the calibration on the longer focal lenght is the best way, as it was pointed out already.

Both pictures are f2,8. The first is 50mm and the second 16mm

Hope it helps

So, to me, it apears to be a very good reason to update the camera, aren't? :lol:

If money are some issue (wich, honestly, doesn't look to be the case), try to find one K-5IIs or one K-3. They are cheap now and very fine cameras that will work fine with the DA150-450.

Agreed with your point on franken-cameras, but I can see some design similarities between the MZ-1 and KP.


Remove the flash, put some retro design dials and ban!, we will end up with something like the MZ-1.


I think manny would buy it.

Yes it's necessary and will affect operation.
There are two metal rings in both sides of the zoom and focus rings that works as a frictionless ring to ensure smooth rotation. If you remove one or both, the rings will get stiff to rotate and will break the new o-ring seal, canceling the wheather sealing capabilities of the lens.

K3ii replacement

Better Low light AF will benefit not only low light photography, but camera behavior as a whole.
Af will be more responsive in good light photography too. Better algorithms, that would be calibrated for lower light levels will allow much more precise AF in either light conditions.
Better low light will allow Pentax cameras to be more competitive in the pro market. The low light performance of the K1 was one of the main gripe with some camera reviewers out there

Been owned a K10d, a K5, a K5ii and now a K3, I can assure better low ligth af make the camera much more usable in general photography. The difference from K5 to K5II was night and day (pun intended).

I'm a freelancer photojournalist that worked a lot in night clubs and now do a lot of night time assignements and I can garantee you people that a better low light AF makes a LOT of difference.

I think that would be a good improvement, if they can deliver it.

This looks like a video capture. Wich is as bad as a bad cellphone pictures...

I've also have seen a trend nowadays with some news sites doing this with all those 4k videos of news covering.

Another big problem are photo selection. Even if there is good photo coverage, either by newspaper's staff photographers or agency freelancers (my case), those news outlets doesn't seen to been able to pick the good pictures.

Brazil's photojournalism has been criticized latelly because of the poor photo selection of major protests. Either photographers and photo editors are doing a bad job of selecting relevant pictures from those assignments. It's really sad, because you do your best to get a great picture and they buy and publish the boring ones. Or hunts for the 'big crowd picture' as they say.
